- is the range of cells that makes up the list or database
- shows which column is used in the function and
- is the range of cells that contains the specified criteria.
- DSTDEV(), estimates the standard deviation based on a sample of selected database entries.
- Standard deviation shows the variation of data points from the average value.
- If data points are close to mean value, a low standard deviation is observed. If data points are spread out from the mean value, a high standard deviation is observed.
- A argument can be expressed as "Salary" (a column name) or 3(position of the column).
- can be any range on the Calci with minimum of one column and at least one row indicating the condition.
- The columns should not overlap the list of data.
Consider the following table with Employee details as input to DSTDEV function.
=DSTDEV(A4:C10,"Age",B1:B3) : Calculates the standard deviation for 'Age' column
in the range A4 to C10, for the cells with 40>Age>30.
Returns 5.214829282387338 as a result. =DSTDEV(A4:C10,3,D1:D2) : Calculates the standard deviation for 'salary'
in the range A4 to C10, for the cells with Age>32.
Returns 1981.161275615895 as a result.
